Sayyiduna Abu Qatadah (may Allah be pleased with him) reports that the Messenger of Allah (peace and blessings be upon him) said: When any of you drinks water, he should not breathe into the vessel, and when he goes to the toilet, he should not touch his private part with his right hand, nor should he clean himself with his right hand.
